GRAIN BIN.

Laissez.

Application filed May l5,

To all whom t may concern Be it known that l. ALLEN lV. JOHN- soN, acitizen of the United States, resident oi YAnoka, county of Anoka, Stateoit Minneseta, have` invented certain new and useful Ylmprovements inGrain Bins', oit which the following is a specification.

The object ot my invention is to provide a grain bin of concrete blockconstruction,

l() divided interiorly into a series of triangular bins, so arrangedthat the lateral pressure of the grain will be transmitted to theoutside walls of the bin, provision also being made for delivering thegrain from the bins to a l5 chamber beneath them or to a wagon on theoutside ot the structiue.

A further object is to provide a bin of inexpensive durable constructionand one which will be lireprootl and easily accessible at the top orbottom.

The invention consists generally in various constructions andcombinations, all as hereinafter described and particularly pointed outin the claims. n

ln the accompanying drawings forming part of this specification,

Figure l is a vertical sectional View through a grain bin embodying myinvention.

Figure 2 is a horizontal sectional view on the line 2-2 oit Figure l,

Figure 3 is an elevation of the lower portion of the bin, showing themeans for admission to the chamber beneath the bins,

Figure 't is a sectional view on the line i-Jl of Figure 3.

In the drawing, 2 represents a suitable toundation and 3 the lower wallsolf the bin, composed preferably of concrete blocks laid one uponanother in the usual way and provided with an interlocking jointlbetweentheir longitudinal abutting edges. These lower walls are carrieda suitable distance above the ground line and support a slab 5 ofconcrete, suitably reinforced in any pretei-red manner and forming thetloor of the bin proper. The upper walls 6 of the bin formed in the samemanner as the lower walls, rest upon the floor 5 and are carried to thedesired height to form a circular bin which is closed at the top by asuitable roof 7 having a central opening 8 that is normally closed by ahinged cover 9. Through this opening access may be conveniently had to`the inside of the structure. The space within the upper wall 6 and abovethe tloor 5 is divided by partitions l0, 10a, 10b, and lOc.

These partitions extend across the I space above the floor 5, dividingit into a series of bins ll, each bin being` in the form et the sectorof a circle, a portion oit the outer wall ot the structure forming onewall oit the bin and two oit the partitions 'forming the other walls.Each inner wall of a bin is laterally braced by the walls oit the otherbins so that when a bin is filled with grain, the lateral thrust orpressure thereof will be transmitted through these partition walls tothe curved outer walls or the structure and will be braced and supportedthereby. The bins are provided with bars 12 at intervals having theirends embedded in the partition walls and forming steps :for ascendingthe rails of the bins or to enable a person to enter the opening in theroot of the structure and descend to the bottom of any one of the bins.The floor ot each. bin is provided with a vertical discharge spout 13leading to the chamber la beneath the bins and each spout is providedwith a suitable valve 1.5 by means of which the iiow oi grain from thebins may be regulated. Access to this space beneath the bins is readilyobtained through the door opening 16 in the lower walls of thestructure.

l also prefer to provide inclined spouts 1T in the walls of thestructure above the iioo-r 5 so that the material in the bins can bespouted out to a wagon box or other suitable receptacle, it desired,these spouts being equipped with suitable regulating valves 18. Thisstructure is made in various sizes and in various ways the details ofconstruction herein shown and described may be inodiiied and still bewithin the scope of my invention.

l claim as my invention:

l. A structure of the class described having a foundation and lowerwalls and a horizontal floor supported thereby above the lower portionof said walls forming a chamber in the base of the structure, the upperwalls of said struct-ure encircling a-chamber adapted to receive grain,said grain chainber having vertical partitions extending from the wallsto the center thereof and dividing the interior space into a series oftriangular bins, said iloor ormin the bottom oit' said bins and saidpartition transmitting the lateral pressure of the grain in one bin tothe outer walls of the structure, the floor of said bins having verticalolischarge spouts therein leading to the chamber beneath said floor andsaid chamber having a door in its wall for access thereto. and the outerwalls of said bins near said loor having outwardly and downwardlyinclined spouts communicating respectively with the bins :fordelivering` the contents thereof outside the structure to a wagon orother receptacle.

2. A structure of the class described having a foundation and lowerwalls and a horizontal floor supported thereby above the lower portionot' said walls torining;- a chain ber in the base olf the structure, theupper walls of said structure encircling a chamber adapted to receive`grain7 said grain chamber having` vertical partitions extending 'tronithe walls to the center thereof and dividingv the interior space into aseries oil triangular bins, said floor loriningr the bottoni ot saidbins and said partition transmitting the lateral. pressure oi. the grainin one bin to the outer walls of the structure, the 'Hoor of said binshaving vertical discharge spouts therein leading to the chamber beneathsaid floor and said chamber havinga door in its wall for access thereto,and the outer walls of said bins near said floor having outwardly anddownwardly inclined spoiits communicating; respectively with the binsfor delivering the contents thereof outside the structure to a wagon orother receptacle, bars mounted in said partitions in the angles betweenthein for ascending the bins on the inside and said structure having aroof and a central opening and cover therefor through which access maybe had to said bars and bins.

3. A structure of the class described coniprising a cylindrical wallhaving a icounda tion, a flat horizontal floor supported by said walland forming therewith a comparatively large chamber in the bottoni ot'the strncture, the upper portion of said wall having a. roof and acentral opening` therein7 and a space between said roof and floor havinc:i series of diagonal partitions dividing;- it into a plurality ofvertical triangular shaped. bins, said horizontal `floor having` spoutstor conductingthe contents of said bins to the chamber beneath saidfloor and the outer walls of said structure having spouts near said doorfor delivering the contents of said bin on the outside of saidstructure, said vertical partitions intersecting at the center of thestructure and transmitting' the load in said bins laterally to the outerwalls thereof.

In witness whereof, I have hereunto set niy hand this 4th day of May1920.

ALLEN D. W. JOHNSON.
